PERIODO: MAGGIO
Il corso si propone di fornire le conoscenze di base sulla struttura cristallografica delle sostanze cristalline e sull'interazione della radiazione X con la materia. Particolare attenzione sarà dedicata alla diffrazione di raggi X da materiali cristallini, fenomeno che è alla base di una delle tecniche di caratterizzazione microstrutturale di più ampio utilizzo.
PERIOD: MAY
The course aims to provide the basic knowledge on crystallographic structure of crystalline substances and on the interaction of radiation X with the matter. Particular attention will be spent to X-ray diffraction by crystalline materials, a phenomenon that is at the basis of one of the techniques of microstructural characterization of wider use.
Conoscenze di matematica, fisica e chimica acquisite durante il percorso universitario.
Knowledge of mathematics, physics and chemistry acquired during the university course.
